We're all aware of the most powerful tool in statistics- THE STANDARD DEVIATION, we seem to forget when we quote percentiles. Your 28% of doubles may have a percentile range of 24-32 , how do you factor this in selecting picks or waging?

The standard deviation doesn't necessarily change what I'm looking at, the future. Standard deviation will have the potential to be greater the smaller the sample size. The problem is, there isn't a way to predict which way and to what degree standard deviation will go until you've seen it. The only thing you can say is that in the future, the probability is that 27% (there are 270 doubles combinations out of the 1000 possible combinations) of the draws will include a double. The farther out you go, the more likely it will be closer to that.

I mostly use it to determine how often I can generally expect to win over a certain period of time. I don't see when I would care that 27% of the time doubles hit unless I was playing all of the doubles. Playing a double boxed just gives you 3 of the possible 1000 combos.

The median skip of P3 digits is 2, so 50% of the time the DD should be a digit at skip 0,1, or 2 (ie, hit in the last, last 2 or last 3 draws). The other 50% of the time the DD will be a digit with a longer skip than 2.

I did that research for the period of Feb. 2005- Aug. 2011 in my state. The percentages I got may have changed since then, but that's what it was at the time.
